A&E Specifications The mixer shall be a compact, rack-mountable digital mixing solution without physical fader strips, but shall include 16 mono and 3 stereo line input channels mixing to 12 mix outputs and 4 stereo rack FX engines, 4 DCA groups and 4 Mute groups. All output mix channels shall contain Insert, Parametric EQ, Graphic EQ, Compressor, and Delay. Signal delays in the system shall be adjustable in Milliseconds. Pre/Post fader routing and assignments, processing of signals, level sends, FX sends, DCA and Mute Groups shall be accessed and adjusted via a 5-inch colour touchscreen provided on front panel of the mixer or from Apple ios touchscreen devices. There shall be a Channel page on the touch screen replacing physical fader strips with different tabs providing access to Input Channels, FX, Groups, Mixes, DCA and Mute Groups and control of level, mute, pan and PAFL for the selected channel. And fully-customizable page giving access to channels and settings tailored to the user and the specified application. Several widgets shall be assigned to this page, these shall include channel levels, mutes and assignment on/off switches and shall be arranged to suit the user requirement. The front panel of the mixer shall include 16 custom select keys and indicators, giving access to any combination of user defined input channels, output channel mixes, FX sends, FX returns or Main mix and also 15 assignable SoftKeys giving access to DCA mute masters and MIDI control as well as Tap Tempo, Instant Scene Recall/Navigation or PAFL Clear. There shall also be dedicated keys for quick Copy/Paste/Reset of mixes and processing parameters. The name and number of the selected channel or mix shall always be identified on screen when in the processing or routing pages. The mixing system shall include application software for Apple ios touchscreen devices connecting via a wireless network router to an Ethernet LAN port. The application shall allow control of functions including the preamp gain, phantom power, mix channel levels and shall have a graphical representation of physical controls and indicators including signal processing parameters and shall provide control of channel processing including Parametric EQ, Graphic Eq, Compressor and Delay. Routing assignments and level adjustments of input signals to all mixes and bus shall be provided and the application software shall provide signal metering and processing threshold indication when online including the Real Time Analyser. Real Time Analysis metering shall include a spectrogram to allow for accurate monitoring of audio energy across the frequency spectrum over time for the purpose of feedback detection and correction of room acoustics. A global source option for the direct out of each input channel shall be provided in the routing screen. The tap-off point shall be adjusted to the following positions in the processing path: post Preamp, post HPF, post Gate, post Insert return, post PEQ, post Compressor, and post Delay. There shall be further global options for Follow Fader, and Follow Mute. Direct outputs shall be assignable via the mixer soft patch bay to any physical output socket interface channel or ME monitoring channel. 4 Stereo Audio Groups shall be available for sub mixing and the combined processing of selected input channels. These Audio Groups shall be switchable to function as additional Send Mixes when required. A signal generator shall be provided with the ability to send a variable level signal to any output mix with visual assignment status on-screen. The following types of signals shall be available: Sine, White Noise, Pink Noise, and Band-Pass. Comprehensive input, output, and FX channel and RTA metering shall be provided onscreen. A Channel Ducker shall be provided to reduce the level of selected channels when a designated channel is in use. This channel priority shall be available across all mono and stereo input channels and also channel groups. An Automatic Mic Mixer shall be provided for automatic level control of up to 16 microphones using a constant gain sharing algorithm to dynamically adjust the gain for each mic in spoken word applications 4 user-assignable effect racks shall be provided with a library of factory preset FX emulations. The FX racks shall be individually configurable as send/return from a channel or FX/Mix, or inserted into input or output channels. A Talkback facility with the ability to send to any output mix with on screen status indication and an option to enable talkback latching and HPF shall be provided. A default Mains to PAFL sub-mix and a stereo quarter-inch jack socket for PAFL headphones output shall be provided, with an analogue output level control. The mixer shall include stereo and 18-track recording/playback to optional USB hard drives. The format shall be 48 khz/ 24 bit WAV. The mixer shall also play back stereo WAV files at 44.1 or 48 khz and have a USB Type-A connector on the surface for recording, playback, data-transfer, archiving, and firmware updates to USB drive. On the rear panel there shall be a Type-B USB connection following the high-speed USB 2.0 standard for multi-channel, bi-directional audio streaming of 32 out / 32 in and MIDI DAW control between the mixer and a computer. DAW transport control using popular DAW control protocols for computer shall be available via the touch-screen. The mixer shall provide a Fast Ethernet (100 Mbit/s) port for Cat5 cable connection to a wireless router (access point) for MIDI over TCP/IP control of mixer parameters via Apple ios touchscreen devices for live mixing control. There shall be a local dsnake Cat5 Ethernet audio expansion port with locking Ethercon connector, providing up to 38 input signals and 20 output signals, plus 40 personal mixing sends to be connected over a single cable digital snake and allowing Remote Preamp control to an Allen & Heath AudioRack, or Allen & Heath ME Personal Mixing Systems. Input and output channel processing and parameters in the mixer shall be saved on demand as a user library item for recall in other channels. Individual processing sections shall be save-able on demand as user library items for that type. All library items shall be stored on board and archived with the show-file. Library items shall be transferrable to USB drive as portable data to be used in other systems. The mixer shall provide the facility to save 100 scenes of the settings of the mixing system and these scenes shall be nameable. A comprehensive table of Scene Safes shall be provided to prevent selected items from being changed from their state when the safe was enabled. A comprehensive scene filter shall be provided per scene to Allow / Block each parameter saved in a scene from being changed as that scene is recalled. An option shall be provided for password protection for log-in of several users with different levels of system access and permissions. A particular scene may be chosen to be recalled per change of user-login if desired. The mixing system shall periodically record all current settings and return the mixer to that state after reboot following a power-cycle. The mixer shall have a built in power supply accepting AC mains voltages of 100~240V, 50/60 Hz, 55W max via an earthed 3-pin IEC male connector mounted on the rear chassis. A Two Pole Push- Button switch shall be provided near the mains input. The mixer shall have an optimised fan-less airflow design for silent operation. Recommended operating temperature for the mixer shall be 5 to 35 degrees Celsius. The mixer shall be the Allen&Heath Qu-Pac Digital Mixer.
